Flexible PU foam is soft and bendable, making it ideal for cushioning and comfort applications like mattresses and upholstery. Rigid PU foam is firm and provides structural support, commonly used in insulation and packaging to provide protection and stability.
Polyurethane foam can potentially trigger allergic reactions in some individuals due to its chemical composition and off-gassing. It may not be considered hypoallergenic for those sensitive to chemicals or respiratory irritants.
Foam mattresses are typically made from polyurethane foam, memory foam, latex, or a combination of these materials. These materials are derived from petroleum-based chemicals for polyurethane foam, rubber trees for latex, and other synthetic materials for memory foam.
Foam beds typically consist of several layers, with the top layer being memory foam or polyurethane foam for comfort and pressure relief. The middle layers may include transition foam for support and weight distribution. The base layer is usually high-density foam for durability and stability. Some foam beds may also have additional layers such as cooling gel foam or latex foam for temperature regulation and added comfort.

For rigid polyurethane, I've seen 1.05 g/cm3 published on the web, which would be about 65 lb/ft3. For flexible poyurethane foam, it varies with how much air is in the foam.
Polyurethane foam are not naturally fire proof but their fire retardant properties can be improved by introducing compatible fire retarding chemical(s) into the formulation. specialised polyurethane products such as in cars, aircraft, ships and so on must be loaded with chemical additive having Fire retardant properties.

Polyurethane Foam as it can be cast, carved and sculpted, finds its uses in many applications in seating, insulation, seals and gadgets, automotive bushings, wheels and tires and more. They are used in filters of air purifiers; Self adherent polyurethane foam paddings are of great surgical use as supports and dressings. Polyurethane foam is used in seating, insulation, adhesives, carpets, plastics and even on vehicles. It is mainly used for insulation purposes as well as fire protection.
The reaction between an isocyanate prepolymer and a polyol in the presence of a blowing agent with an amine as catalyst results in the formation of polyurethane foam. Different types of polyurethane foams like flexible polyurethane foam, rigid polyurethane foam, thermoplastic polyurethane etc. are widely used for a variety of purposes.Polyurethane foams are mainly used in bedding and carpet underlay, furniture, rigid foam insulation panels, gaskets, electrical potting compounds, durable elastomeric wheels & tires etc. With an increase in its applications, the market demand for PU foams is also increasing.There are several general trading companies that are well known to be the leading polyurethane foam suppliers, PU foam scrap supplier, polyurethane trim foam supplier etc. If you are concentrated in the UAE, the Middle East or African regions, then I would like to suggest the UAE based general trading company Fortune Emirates. They are the regular PU foam scrap supplier, polyurethane trim foam supplier and polyurethane foam suppliers in UAE. You can avail quality PU materials from this polyurethane foam supplier in UAE at pocket friendly prices.
CPI spray is made of Polyurethane Foam. Polyurethane Foam is made by adding water to polyurethane plastics.

Absolutely. You can buy polyurethane foam at a place like this: http://www.uscomposites.com/foam.html
The medical uses of Polyurethane Foam include wound dressings for exudating wounds. You can see a list of them at http://www.thomasnet.com/products/polyurethane-foam-30683502-1.html
Polyurethane foam can be cleaned with a mixture of vinegar and water. Pour the solution on a soft cloth and rub the foam, rinse, and let dry.
Polyurethane will kill you if you eat it.
